Aircraft Drawing-Die Design CAD Expert System Based on Engineering Graph

摘要

The features of engineering CAD expert systems are discussed and an ADDES system(Aircraft Drawing-Die Design CAD Expert System) is built. Based on the construction of the DIE coding system, such methods as the feature-based code system are used to establish a customer model. The agents in the system have the ability to solve partial problems, and the system is organized into distributed and hierarchical forms. The system synthetically utilizes blackboard structure, meta-reasoning and so on to control the problem solving process. As discussed above, the problems such as low efficiency etc caused by building a large knowledge base can be solved and the cooperation of many experts can be attained.
